Betonline account cancellation - refusal to close until more personal info is shared overseas Internet

I have spent days trying to close the poker account with betonline. The site is corrupt and winning is impossible. When I requested the first time for it to be closed they said not until it is in writing. That was provided and then was told not until you provide birthdate and social security. Like a fool I provided it wanting the account closed. Now they have refused to close it because they want my physical address and phone number. Everything needs to be in writing and at this point I've provided so much information they could sell it to anyone to steal be blind. Not to mention, I have four account numbers on file with them. Bottom line, they won't close the accound! It is rediculous!
